Heh.

They basically all work off the same meta list of subrules. _2 is 2+ hits,
_3 is 3+ hits, etc. Then to those some FP-avoidance checks are added.
There are variants for N hits plus a LOTSA_MONEY hit or a FILL_THIS_FORM
hit or both, but in all there are only about twelve variants to score. The
meta list of subrules is generated by a GA rule generator (which I haven't
run in a while) off the list of candidate rules and my 419 corpus.

Correct. And changes can affect the scoring.

The basic set of subrules changes, and I'm open to additions, but the mtea
for the ADVANCE_FEE rules is generated by a GA process.

I don't have a problem with statically scoring them, in fact that's what
the static sandbox score file was intended to address. I don't know if
that's the _best_ way...

I too would like to see a way to assign a minimum score. The GA rescorer
seems to do some very counterintuitive things at times, and it would be
conforting to have a way to control it a little better.
